IMPROVEMENT IN RAILWAY JOURNAL-BOXES.

Specification forming part of Letters Patent No. 117,753, dated August 8, 1871.

To all whom it may concern:

Beit known that I, ISAAC DRIPPs, of Altoona, in the county of Blair and State of Pennsylvania, have invented a new and useful Improvement in J ournal-Boxes for Railroad Gars; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure l is a vertical longitudinal section of my improved journal-box. Fig. 2 is a vertical cross-section ofthe same. Fig. 3 is a detail view of the inner end of the same, showing the axle in section. Fig. 4 is a detail top View of the detachable plate that holds the bearing or brass. Fig. 5 is a detail top view of the bearing or brass.

Similar letters of reference indicate corresponding parts.

My invention has for its object to improve the construction of journal-boxes for railroad cars, so as to prevent heating and irregular wea-r, while allowing the journal to have the play necessary for running around curves or upon uneven tracks; and it consists in the construction and combination of various parts, as herein after more fully described.

A is the casing, housing, or shell, which is connected with the car in the ordinary manner, and through an opening in the inner end of which the journal B passes. The cotton-waste and lubricating material are inserted through an opening in the upper part of the outer end, which opening is closed with a lid or cover, C, which has lugs formed upon its upper edge, through which passes a bolt, c1, which also passes through lugs formed upon the casingA to hinge the said lid or cover C to the said box A, land thus guard against the possibility of the cover being lost. The cover Gis secured to the box A when closed by the button c2, which is made in about the form shown in Fig. 1. D is the bea-ring orbrass that rests upon the journal B, and which has an upwardly-projecting part or piece, d1, formed upon the rear end of its upper side. The forward edge of the projection d1 is concaved, as shown in Fig. 5, to fit into a correspondinglyv` shaped recess, e1, formed in the inner end ofthe lower side of the plate E. The sides of the bearing or brass D have rounded projections d2 formed upon their middle parts, which t in between the projecting Iianges or guides e2, formed upon the edges of the lower side of the plate E. The plate E has a recess, e3, formed across the middle part of its upper side to receive a projection, al, formed across the under side of the top of the box A, as shown in Fig. l. By this construction the rear end of the bea-ring of brass box D rests against the inner end wall of the box A, which prevents the inward movement of said bearing D. The outward movement of the bearing D is prevented by the projection d1 pressing against the curved sides of the recess el. The curved projections d2 of the bearing D rest against the iianges e2 of the plate E, allowing the .bearing D to rock horizontally with the lateral movement of the car-axle. The bearing or brass D is kept in place sidewise in plate E by the flanges or guides c2 of the plate E. The flanges e2 also add stiffness to the plate E. The under side of the top of the box A is a curved surface from the outer end of the top of the box A to the inner end wall of the same, to allow the plate E and bearing D to rock vertically with the vertical movement of the car-axle. The projection a1, at or near the center of the curved surface a at the top of the box A, ts into the recess e3 of the plate E, which prevents the plate E from moving forward or backwardl in the box A. F is a ring of leather packing, which fits upon the enlarged part of the axle B, and which fits upon and rest-s against the outer side ofthe inner end of the box A, where it is held in place by the sectional U-shaped ring or plates G H, the legs of which overlap each other, as shown in Figs. l and 3. The plates G H are secured to each other and to the box A, clamping the leather ring F between them and the inner end of the said box by the long bolts I, which pass longitudinally through the box A through slots in the legs of the plate H and screw into screw-holes in the legs of the plate G. The under end of the box A is thus kept oil-tight. The escape of oil at the rear end of the box A is still further guarded against by the leather iiaps K, one or more, the upper edges of which are concaved to fit upon the lower side of the journal B, and which have holes formed through their upper ends for the passage of the bolts I, so that the said flaps may be suspended from the said bolts. The flaps K are pressed and held against the inner surface of the inner end of the box A by flap K concaved on its upper edge, and the bolts I I passing therethrough to prevent the sediment or coarser particles from Working between the inner annular flange of the box and the journ al.
